Question 1

How do I map Swift structs to MySQL tables with OHMySQL?

Accepted Answer

You need to implement the OHMappingProtocol for your models, but note that Swift types like Int must use NSNumber. The README recommends writing custom mapping logic for better control, which adds development overhead.

Question 2

Is OHMySQL thread-safe for concurrent database access?

Accepted Answer

The documentation doesn't explicitly address thread safety. Since it's built on MySQL C API, you must manage concurrency yourself, such as by using serial queues or ensuring connections are properly synchronized.

Question 3

OHMySQL vs using the raw MySQL C API in Swift?

Accepted Answer

OHMySQL abstracts the low-level C API, offering a Swift-friendly interface that reduces boilerplate. However, for performance-critical apps needing fine-grained control, direct C API usage might be better, though more complex.

Question 4

Can I use OHMySQL with async/await in Swift?

Accepted Answer

No, OHMySQL doesn't natively support async/await as it's built on synchronous C API calls. You'll need to wrap operations in DispatchQueues or completion handlers to integrate with modern Swift concurrency.

Question 5

How to handle connection errors with OHMySQL?

Accepted Answer

Error handling uses Swift's try-catch blocks, as shown in examples with 'try?'. For production apps, implement robust error catching and logging, but the framework provides limited built-in error recovery mechanisms.

Question 6

Does OHMySQL support connection pooling for efficiency?

Accepted Answer

The README doesn't mention connection pooling. You'll need to manage connections manually, which could lead to inefficiencies in high-load scenarios unless implemented externally.
